What Our Customers Say

Just completed our granny flat yesterday. What service! Every tradie and staff member we dealt with were fantastic, professional and courteous. Our supervisor Johno was brilliant to deal with, can’t rate these guys highly enough. A huge thank you from

Dave and Isabel

We recently had our patio done, and we couldn’t be happier with the result. From the very beginning, our consultant Rob was incredibly friendly and took the time to explain everything in detail. He made the whole process easy and stress-free, from design to planning.

Emily S

We are in the process of building a granny flat in the Mandurah region. Our sales person, Kevin De Santos at the Canning Vale showroom, has been outstanding. His communication and ability to switch plans around has made the design part extremely easy. I would highly recommend him.

Everything you need to know before you visit, from pricing and council approvals to build times and what is included.
How much does a granny flat cost in Perth?

Granny flat pricing in Perth varies depending on the size, design and your site conditions. Our range starts from compact studio designs through to spacious 2 bedroom models. As a rough guide, most turnkey builds sit between $80,000 and $185,000 or more. The best way to get an accurate figure is to visit one of our display centres in Joondalup or Canning Vale. Our team will give you a detailed quote based on your block and the model you choose.

Yes. In Western Australia, most granny flats require both a Planning Permit and a Building Permit from your local council or the WA Planning Commission. The requirements vary depending on your block size, zoning and the size of the dwelling. Classic Granny Flats and Patios handles all council approvals and permit applications on your behalf, so you do not need to deal with the paperwork yourself.
The total timeline from first visit to handover depends on the council approval process in your area, which typically takes between 8 and 16 weeks. Once permits are approved, the physical build is generally completed within a few weeks. Classic Granny Flats and Patios team will give you a realistic timeframe once we know your location and the model you have chosen.

Classic Granny Flats and Patios all-in turn key pricing covers everything you need from the start: design and drafting, all council permit applications, site preparation, construction, floor coverings, paint, bathroom fit-out, kitchen, and full electrical and plumbing hook-up. There are no hidden extras. The price you are quoted covers the complete finished dwelling ready to move in.

Most Perth blocks can accommodate at least one of our models, and our range includes compact studio options from 15m2 for tighter sites. Our team will assess your block dimensions, setback requirements and zoning to confirm which designs are suitable. We can also custom design to suit limited spaces or accessibility requirements. Bring your property details to our display centre and we will walk you through the options.

Yes. Both our Joondalup and Canning Vale display centres are open Mon – Fri: 9:00am – 4:00pm and Saturday to Sunday 10:00am to 1:00pm. Walk-ins are welcome. You can browse the 12 full-scale models at your own pace, and our team is on hand if you have questions. No pressure, just honest advice.
